1 Claim.

The present invention relates to a machinethat deposits a liquid lining material in the gutter of a rotating can cover or the like and in which the several portions of the gutter are at different distances from the center of rotation of said cover, the liquid lining material being suppliedby a nozzle that is moved back and forth to follow the contour of Said gutter. The liquid lining material is of a character that solidiiies quickly so as to produce a sealing gasket in the gutter, and the main object and feature of the invention is to assure the production of a gasket of substantially uniform thickness throughout the gutter.

In the accompanying drawings the invention is disclosed in a concrete and preferred form in which:

Fig. 1 is a vertical longitudinal sectional view through the machine, substantially on the plane of line I-I of Fig. 2.

Fig. 2 is a sectional plan view substantially on the plane of line 2-2 of Fig. 1 with the nozzle and its actuating means superposed thereon.

Fig. 3 is a vertical transverse sectional View substantially on the plane of line 3-3 of Fig. 1.

Fig. 4 is a vertical sectional View through a part of a can cover showing the gutter and the relation of the nozzle thereto.

Fig. 5 is a diagrammatic plan view of a can cover showing it in different positions as it rotates and the relation of the nozzle with respect thereto.

Fig. 6 is a diagrammatic view showing the development of a cam that constitutes a variable speed device.

Fig. 'l is a detail view looking in the direction of arrow 'l of Figs. 2 and 9.

Fig. 8 is a detail sectional view substantially on the plane of line 8--8 of Fig. 7.

Fig. 9 is a detail sectional View substantially on the plane of line 9 9 of Fig. 7.

Referring iirst to Figs. 4 and 5, numeral I) indicates the can cover having a gutter II, the several portions of the latter being at different distances from center of rotation I3. I4 is a nozzle which is moved back and forth to follow the contour of the gutter and which deposits liquid lining material I5 in said gutter. In the exempliiication shown, the cover and gutter are substantially rectangular shape. It will be understood from a consideration of Fig. 5 that if the angular speed at center of rotation I3 is uniform, then the surface speed at which the several portions of the gutter passes the nozzle is non-uniform because of the differences in distance of the several portions of the gutter from said center of. rotation and consequently the deposition of the lining material will be nonuniform.

Referring now to Figs. 1, 2 and 3, I6 indicates 5 a rotatable support on which the can cover is placed either by hand or fed to and removed therefrom by suitable means that form no part of the present invention. Nozzle I4, connected by ilexible hose II to a source of supply of liningl 10 material (not shown) is mounted on a reciprocating carriage I8 that slides in guides I9 and receives its motion from cam 2D by means of suitable connections including cam roll 2l. Cam 20 is mounted to rotate at the same speed as cover support I6 and has precisely the same contour as gutter II of the cover. Any suitable variable-speed driving means to accomplish the intended purpose can be used to rotate cover support I6 and cam 20. 20

Referring now more particularly to Figs. 1, 2 and 6 to 9, in the present instance, 22 indicates a rotatable cam that turns sprocket wheel 23 intermittently by means of rollers 24 carried by said sprocket wheel. Sprocket Wheel 23 is ar- 25 ranged with its axis at right angles to that of cam 22 and transmits its motion by means of chain 25 to sprocket pinion 26 which latter drives both rotatable support I6 and nozzle cam 23 which latter is coaxial with said support and car- 30 ried by the same shaft. Power is in the present instance supplied to the machine from motor 2l, by way of pulley 28, belt 29, pulley 30 on shaft 3|, carrying worm 32, engaging worm Wheel 33 on shaft 34 carrying cam 22. 35

It will now be understood that continuous rotation of cam 22 produces an intermittent rotation of sprocket wheel 23 at variable speeds depending upon the shape of cam groove 35 of cam 22. Rotation of sprocket wheel 23 causes, 40 through chain 252 rotation of sprocket pinion 26 and thereby rotation of cover support I6 and cam 26. Rotation of cam 20 causes reciproeation of carriage I8 that supports nozzle I4. It will further be observed that cam 22, in addition to 45 active cam groove 35, is provided with inactive portions 36, and with open portions 31 to permit rollers 24 to enter and leave cam 22 sidewise in response to the turning movement of sprocket 23. 50

As a result, all portions of the gutter of the cover, at the moment they pass the nozzle, move relative to the nozzle at identical speed, notwithstanding difierences in distance of the several portions of the gutter from the center of rota- 55 tion of the can cover, and, further, that the nozzle moves back and forth, in a straight line only, at variable speeds to maintain the nozzle over any portion of the gutter that is passing said nozzle.

I claim:

In a machine for depositing a liquid lining material in the gutter of a rotatingv can cover, the several portions of said gutter being at dif- Iferent distances from the center of rotation of said can cover, and in which a nozzle moves back and forth to follow the contour of the gutter,

means to cause al1 portions of the gutter at the moment they pass the nozzle to move relative to the nozzle at identical speed notwithstanding diiferences in distance of the several portions of the gutter from the center of rotation of the can cover, and to cause the nozzle to move back and forth in a straight line only, at variable speeds to maintain the nozzle over any portion of the gutter that is passing said nozzle, including: a rotatable support for the can cover; a cam and connections to effect back and forth movement of the nozzle, said cam of a shape that corresponds With the contour of the gutter; and variable-speed driving means and connections to rotate said support and cam at speeds to compensate for variations in distance of the several portions of the gutter from the center of rotation of said support.
